Working Principles

The SN75176ADRG4 is a differential bus transceiver designed for RS-485 and RS-422 communication standards. It uses differential signaling to transmit and receive data over long distances, providing noise immunity and reliable communication in industrial environments. The driver section converts logic-level signals into differential voltage signals, while the receiver section converts the received differential signals back into logic-level signals.
